The fixedmold part 110 has afirst molding surface 112 defined on one surface thereof facing towards themovable mold part 120. Themovable mold part 120 has asecond molding surface 124 defined on one surface thereof facing towards the fixedmold part 110. Thefirst molding surface 112 is aligned with thesecond molding surface 124 and a molding chamber is defined therebetween. Twofixing blocks 127 are formed on themovable mold part 120 and twolocation holes 116 corresponding to thefixing blocks 127 are defined on the fixedmold part 110. Thefixing blocks 127 are matingly engaged in thelocation holes 116 to give themolding apparatus 100 good concentricity. However, the concentricity of themolding apparatus 100 may lessen after repeated sinking and re-assembly of the fixedmold part 110 and themovable mold part 120 due to wear and tear on thefixing blocks 127 and the fixedmold part 110. - What is needed, therefore, is a molding apparatus that can produce a greater number of products with constant and accurate concentricity and/or precision.
- In a preferred embodiment of the present invention, a molding apparatus includes a fixed mold part, a movable mold part and a movable core module. The fixed mold part includes a first mold core and a frustoconical recess defined therein and has a first molding surface in the frustoconical recess. The movable mold part is configured for alignment with and attachment to the fixed mold part and defines a first through hole therein and is shaped so as to conform with a shape of the frustoconical recess. The movable core module is received in the first through hole and includes a main body having a frustoconical protrusion with a receiving hole defined therein, and a second mold core received in the receiving hole in the frustoconical protrusion. The second mold core has a second molding surface, and the frustoconical protrusion is configured (i.e., structured and arranged) for extending through the first through hole of the movable mold part and being matingly engaged in the frustoconical recess. The first molding surface can thus be aligned with the second molding surface and defines a molding chamber therebetween.

- FIGS. 1 to 3 illustrate a
molding apparatus 200 in accordance with a preferred embodiment. Themolding apparatus 200 includes a fixedmold part 210, amovable mold part 220 and amovable core module 230. - The fixed
mold part 210 is arranged facing themovable mold part 220. Afirst mold core 270 and afrustoconical recess 212 are defined in the fixedmold part 210. Thefirst mold core 270 has afirst molding surface 2702 in thefrustoconical recess 212. Thefirst molding surface 2702 and thefrustoconical recess 212 are both adjacent to themovable mold part 220. - The
movable mold part 220 is configured for alignment with and attachment to the fixedmold part 210 and includes a movable coremodule receiving part 2202 and abase part 2204. The movable coremodule receiving part 2202 and thebase part 2204 define a first throughhole 222 and a second throughhole 224 therein separately and each should preferably include a stepped structure in thethrough holes module receiving part 2202 and thebase part 2204 can be coupled together with a plurality ofbolts 250. - The
movable core module 230 includes amain body 232 and asecond mold core 242. The main body has afrustoconical protrusion 2322 with a receivinghole 248 defined therein and includes aflange 2326 on an outer surface thereof, which is configured for abutting against the stepped structure in the first throughhole 222. Thefrustoconical protrusion 2322 is configured for extending through the first throughhole 222 of themovable mold part 220 and is shaped so as to conform with a shape of thefrustoconical recess 212. Thereceiving hole 248 is defined in the middle axis of themain body 232 and asecond mold core 242 is received in thereceiving hole 248. Thesecond mold core 242 has asecond molding surface 2422 on one end thereof facing thefirst molding surface 2702. Thefirst molding surface 2702 and thesecond molding surface 2422 can be both spherical or non-spherical. - A supporting
plate 246 contacts one end of thesecond mold core 242 adjacent to thebase part 2204 and is configured for supporting thesecond mold core 242 thereon in thereceiving hole 248. The supportingplate 246 is connected with thesecond mold core 242 by a connecting screw 2442 and is coupled to themovable core module 230 by means of at least an adjusting screw 2444. The adjusting screw 2444 is configured for adjusting a position of the supportingplate 246 relative to themain body 232. A resilient member such as, for example, aspring 260 is arranged between theflange 2326 and thebase part 2204. When themovable core part 220 is assembled, two ends of thespring 260 contact theflange 2326 andbase part 2204 separately and thespring 260 is compressed so as to bring themain body 232 into firm contact with the movable coremodule receiving part 2202. - Referring to
FIG. 4 , thefrustoconical protrusion 2322 is matingly engaged in thefrustoconical recess 212 in a manner such that thefirst molding surface 2702 is aligned with thesecond molding surface 2422 and amolding chamber 280 is defined therebetween. A shape of themolding chamber 280 is that of a molded component with a predetermined shape. In this preferred embodiment, anoptical lens 300 is taken as an example as shown inFIG. 5 . Theoptical lens 300 has two opposing moldedsurfaces first molding surface 2702 and thesecond molding surface 2422 respectively. Centers of sphere of the two oppositemolded surfaces optical lens 300. During molding, molding materials (e.g. glass or plastic) are injected into themolding chamber 280 through a sprue gate (not shown) and then theoptical lens 300 is formed. The second throughhole 224 is configured for allowing access of the adjusting screw there through, therefore, a thickness of themolding chamber 280 can be easily changed. It is to be understood that the twoopposing surfaces optical lens 300 also can be non-spherical. - The
present molding apparatus 200 has a good concentricity even after prolonged use because the frustoconical protrusion is matingly engaged with thefrustoconical recess 212 and less wear occurs between thefrustoconical protrusion 2322 and thefrustoconical recess 212. - It is to be understood that the above-described embodiment is intended to illustrate rather than limit the invention. Variations may be made to the embodiment without departing from the spirit of the invention as claimed. The above-described embodiments are intended to illustrate the scope of the invention and not restrict the scope of the invention.
